Title: Rotary drum type scanner
Inventor: NISHIKAWA MASAHARU
IPC: H04N1/06
Filed: 1984-06-15
Abstract: PURPOSE:To attain high speed scanning and to simplify the constitution of a driving means of a scanning head by forming the scanning head with the inclination of theta angle from the rotary shaft of a rotary drum which is a surface to be scanned and continuously moving the scanning head by interlocking with the rotation of the rotary drum to execute subscanning. CONSTITUTION:Recording paper is wound around the external periphery of the rotary drum 20 to form the surface 21 to be scanned. A guide shaft 22 is arranged in parallel with the drum rotary shaft oppositely to the rotary drum 20 and the scanning head 23 is fitted to the guide shaft 22 so as to be optionally moved. The scanning head 23 is formed by successively arraying 5 scanning elements 23a-23e in the shaft direction of the rotary drum and continuously moved in the arrow (a) direction synchronously with the rotation of the rotary drum 20. Main scanning is executed by the rotation of the rotary drum 20 and subscanning is executed by moving the scanning head 23 by a scanning width DELTAl in the (a) direction during one rovolution of the rotary drum 20. In this case, scanning lines are inclined by theta angle from a reference peripheral line X on the rotary drum 20. Since the surface 21 to be scanned is also inclined by theta angle from the line X, the scanning lines parallel with sides 21a, 21b are successively formed on the surface 21 to be scanned.

Title: Information processing method
Inventor: SHIINA TAKAHIDE
IPC: G06F17/21
Filed: 1995-05-22
Abstract: PURPOSE: To improve the precision of KANA (Japanese syllabary)/KANJI (Chinese character) conversion by registering the reading and the notation of the word to a KANA/KANJI conversion dictionary when the reading and the notation of the word extracted from electronized dictionary information of the dictionary for KANA/KANJI conversion do not exist. CONSTITUTION: When an instruction to generate the dictionary for KANA/ KANJI is given by an input device 1, an input information control part 21 instructs the reading/orthography field information control part 23 to generate the word information on the reading and notation. The reading/notation field information control part 23 extracts only data of the reading and notation from data transmitted from a dictionary data reference part 22 and stores them in the reading/notation field information storage area of a storage device. A KANA/KANJI conversion dictionary generation part 25 judges whether the instructed word exists in the KANA/KANJI conversion dictionary area of the storage device or not, from the reading and the notation of the word, which are transmitted from the reading/notation field information control part 23.  When it does not exist, it is added to the KANA/KANJI conversion dictionary area. When the same word exists, it is not added and a processing is terminated.

Title: Picture interpolating method
Inventor: AOYAMA TOMOO
IPC: G06T15/00
Filed: 1994-06-03
Abstract: PURPOSE:To obtain an expanded picture where features of the original picture remain by calculating a vector in the vicinity of the middle point between two points and calculating a function value on a plane and using random numbers, whose average value gradually approaches 0, to change it and calculating the limit of the function after the change to interpolate the picture. CONSTITUTION:A PE number is recognized, and the base address is calculated. Next, {Ci} on the main storage is accessed, and local {Ci} data is transmitted to a slave PE 21. The slave PE 21 performs calculation based on this local {Ci} data and calculates {Cxsi}. The calculation result {Cxsi} is transmitted to a master PE 20. In this manner, the middle point displacement method of random fluctal logic is used to interpolate the unknown points of the picture, and random numbers whose average value gradually approach 0 are made to act on the set including these interpolated points, thereby obtaining the expanded picture where features of the original picture remain.

Abstract: PROBLEM TO BE SOLVED: To prevent a high surface pressure from locally acting caused by a stone or the like on a pad main unit, by providing a stone sweeping part capable of discharging the stone or the like between mutual elastic pads mounted on adjacent crawler links. SOLUTION: A stone sweeping part 8 capable of discharging a stone 7 or the like is provided between mutual elastic pads 3 adjacent to each other. This stone sweeping part 8 is constituted by providing an extension part 10 toward both sides in the crawler peripheral direction relating to a core material 4 of each elastic pad 3. In this crawler 1, an interval between the mutual adjacent elastic pads 3 is placed in a spread opened condition when the pad is wrapped around an idler wheel and a drive wheel, here the stone 7 or the like is assumed to be picked up. Even in the case thus generated, when these elastic pads 3 are led to a flat mounting part serving as the part between the idle wheel and the drive wheel, the extension part 10 of the core material 4 provided as the stone sweeping part 8 forcedly springs out the stone 7 or the like.  Accordingly, a high surface pressure can be prevented from locally acting on a pad main unit 5 by the stone 7 or the like.

IPC: E02D3/12
Filed: 1994-06-03
Abstract: PURPOSE:To reduce cost by a method wherein a high-pressure fluid is injected as a crossed jet from a pair of nozzles oppositely arranged to a pipe after drilling by a cutting edge mounted at the front end of the pipe while the nozzles are expanded and a pile diameter is controlled accurately. CONSTITUTION:A pipe 6 is rotated and lowered to cut a pit, and a high-pressure liquid is infected into soil from nozzles 71, 72. The nozzles 71, 72 are expanded simultaneously to the outside by air cylinders, etc., and the jets of the high- pressure liquid are crossed at all times. A distance from the center line of the pipe 6 to an intersection T is determined by the angles of opening and closing of the nozzles 71, 72 at that time. The pipe 6 is moved and the height of a pile is controlled in desired height, and a hardener is infected from the nozzles 71, 72 while the pipe 6 is shifted as being rotated, thus forming a consolidation pile using the point T as an outermost edge in the ground. The supply of the high-pressure liquid is stopped, and the pipe 6 is pulled up on the ground under the state, in which the nozzles 71, 72 are placed along the pipe 6. Accordingly, a pile diameter can be formed accurately, and the loss of a material, etc., can be prevented.
